Large Print, Anyone?

I've noticed something that struck me as odd. Many, if not most, authors don't put out books in large print for those who are visually impaired. I realize many people are using e-readers, which allow control over text size. But I also realize I'm not the only reader who prefers a "real" book in my hands, and I have to wonder how many authors are missing out on readership because their books aren't available in large print format as well as standard fonts.

I recognize that traditionally published authors don't necessarily have a say in what formats their books are produced, but we indies DO. Advice I received recently during a seminar on self-publishing stated it simplest - get your books out there in as many formats and to as many venues as you can. Better to sell more copies.

I'm making my books available in both standard and large print paperback. I use Times New Roman-12 pt for my standard format paperback books (also makes it easier to format for e-books), using 6x9 size trade paperbacks. For large print, I use Times New Roman-16 pt. My novella was fine in the same size paperback with Times New Roman-16, but novels get monstrously thick, so I use 7x10 size paperbacks for large print books.

If you use a print-on-demand venue such as Create Space, it doesn't cost you anything but the time needed to change format/font to make your book available in both standard and large print. So why not do it and make your book available to even more people?
